I recently purchased two stainless steel tanks of an all metal design, as opposed to the tanks with plastic lids that I already use. Both tanks are of the design below; one with the capacity of a single '120' film, and one for four '120' films. The cap of the longer tank is rather loose, but the cap for the shorter tank is stuck, and will need some mechanical advantage to release.
Is it possible to tell whether these are the Nikkor brand?
The reels supplied (5) are fully spaced 120 format, but not Hewes brand.
